Form Validation Invisible

We created a larger form with the “Contact Form” module. At the top of the form there are some required fields. You can’t see them, if you scroll down to the submit button at the end of the form. So, if they are not filled out and you press “Submit”, you see nothing happens. The red borders around the fields with missing content appears, but they are not visible in the browser window (because they are on the top of the form). Is there a possibility to show a message like “Attention: Please fill out all required fields” and/or automatically scroll up to the fields with missing content?

Thank you, Jan
